This document proposes a theoretical framework for assessing the sustainability of economic information and communication technology (ICT) strategies. It divides the framework into four levels: technical, industry, social, and environmental. At each level, it lists relevant factors and poses hypotheses about the relationships between the levels and their impacts on greening the economy through ICT. The overarching goal is to develop a holistic evaluation framework that can be tested with stakeholders to guide sustainable economic ICT strategies.
